What problem does it solve? Writing Claude Code plugin agents requires precise YAML frontmatter, well-structured system prompts, and triggering examples, and mistakes in any of these cause agents to fail to trigger or behave unpredictably. ## Core Features & Use Cases - Agent File Authoring: Provides the complete agent markdown format covering name, description, model, color, and tools frontmatter fields with validation rules. - System Prompt Design Patterns: Supplies templates for analysis, generation, validation, and orchestration agents with responsibilities, process steps, and output formats. - Triggering Example Guidance: Explains how to write example blocks with context, user messages, and commentary so agents trigger reliably. - Use Case: When you need a code review agent for your plugin, follow the templates to create agents/code-reviewer.md, then run scripts/validate-agent.sh to confirm the structure and fields are correct. ## Quick Start Create a code review agent for my Claude Code plugin and validate the agent file structure.
